GAS HEATING-RADIATOR.

Specification of Letters ratent.

Patented Aug. 3t, 1915.

Application filed August 17, 1914. Serial No. 857,009;

scription.

My invention relates generally to gas heaters and more particularly tothat type of heater wherein the heat generated is passed through asectional radiator and an air circulation is maintained throughout theradiator by means of suction. One objection to existing heaters of thistype is that the upper part of the radiator becomes so hot that personsor articles, easily afiected by heat, coming in contact therewith areinjured.

The general object of my invention has been to provide a heater in whichthe radiating surface shall be increased and so arranged that thetemperature of all the exposed parts of the radiator Will be restrictedto a degree not exceeding the temperature of a' steam radiator.

Another object has been to provide a radiator in which substantially allof the heat shall be radiated into or absorbed by the surrounding air,and to increase the generating capacity of the radiator without any ofthe heated air being exhausted into the atmosphere. Furthermore, Iprovide in my radiator means for draining the liquid condensation, whichresultsfrom the burning of the gas, and means for maintaining a pressurewithin the radiator which is less than atmospheric pressure. I haveaccomplished the above objects and advantages by the device shown in theaccompanying drawings, forming part of this specification.

In the drawings like characters of reference indicate like partsthroughout the several views of which:

Figure 1 is a side elevation of my radiator. Fig. 2 is an end elevationof the same, partly in section. Fig. 3 is a sectional elevation taken online 33 of Fig. 1 showing the heater box in full, and showsdiagrammatically, in addition thereto, a suitable means for producingsuction within the radiator. Fig. 4 is a fragmentary sectional elevationtaken on line 4-4 of Fig. 1. Fig. 5 is a,

fragmentary sectional view taken on line Y 55 of Fig. 3. Fig. 6 is anenlarged, fragmentary, sectional elevation of the heater box of myradiator.

My radiator comprises heating sections 6 and 6, which are securedtogether by any well known means. Preferably I form my radlator with anequal number of heating sections at each side of the center of the asame, and at the center is provided the heater box 7 of the radiator anda dummy section8, extending around the heater.

Each of the heating sections 6 comprises a central member 9 and anexterior member 10, which latter comprises a front part 10 and a rearpart 10*. The chamber formed by the exterior member 10 of the sectionextends from the lower end of the central member 9, up the front part 10of the radiator, over the top and down the rear part i0 thereof wherethe air is drawn ofi by means of a slight suction. The upper and lowerends of the central members 9 are connected together so that passageways 11 and 12 are formed therebetween. The lower ends of the rear parts10 of the exterior member 10 are also connected together and assage ways13 are formed therebetween. Each of the heating sections 6 is in theform of a double return bend, and the lower end of the rear part 10 ofthe exterior member 10 is not attached to the central member 9, but isspaced apart therefrom so that an additional passage for the atmosphereis provided. The'end sections 6 are each provided with suitablesupporting legs 14, and the lower end of the rear part 10 of theexterior member 10 is attached to the lower end of the central member 9,but the chamber therein by a baffle plate 15 This plate is provided witha small opening 16 at the lower side thereof. The purpose of theseplates is to reduce the quantitv of heated gases which are conducted tothe central members 9 of the end sections 6 By this arrangement thecentral members!) of theend sections are kept at a temperaturesubstantially as low as the restricted temperature of the exteriormember 10.

The heater box 7 does not form part, of my invention, and need be onlybriefly referred to. It is provided with a nipple 17 at each sidethereof, which connects with the adjacent heating section 6, and theheated gases pass through-these nipples into the heating sections 6 and6. 18 is a as mixture supply pipe, which fits into an e ow 37, securedto the bottom of the heater box. I

38 is the burner of the heater box, which 1s carried preferably by theelbow 37 and is supplied with the gas mixture therefrom 39 is thepilotlight of the burner, whlch is supplied with gas from the pipe 19.The

burner box is also provided with radiating ribs 20 and drop air intakes21.

22 is the door of the heater, which rests on the inclined face 40- ofthe heater box and is thus held in place by gravity. This door ispivotally attached to the lower ends of links 41, one disposed at eachside thereof, said links having their upper ends pivotally secured tothe heater box. By this arrangement the door will always adjust itselfto the inclined face 40 of the heater box, and thu seal the jointbetween the door and the heater box against the atmosphere.

The dummy section 8 is of the same general exterior shape as theexteriormembers 10 of the heating sections 6 and 6*, and is disposed about theburner box 7-, thus preventing anything from coming in contact with thehighly heated burner box. The front part 8 of this section is providedwith a pivoted portion 23, which is secured to one of the adjacentsections 6 by means of the hinges 24:. This section is thus arranged tobe swun open so as .to get at the burner box 7. spring catch25 isprovided, having one end preferably secured to an adjacent heatingsection 6, whereby the pivoted portion 23 is retained in position; Thispivoted portion 23 is also provided with a mica window 26, which isdisposed directly in front of the door 22 of the burner box. This windowpermits inspection of the flame of the burner without having to swingthe section open. The portion 23 is similar to the rear part 8 of thedummy secti0n'8, except that the rear wall thereof is removed. The upperstationary portion of the front part 8 of thedummy section also has therear wall removed up to the lower wall of its top 8. The rear part 8 ofthe dummy section 8 is cut off short and i open at the lower end, thuspermitting air to circulate freely through the interior surface and tocome in contact with I the exterior surface of this section. Thus thetemperature of this section is kept substantially as low as that of theexterior members 10 of the other sections. A lug 27 is provided at thelower end of the rear side of the dummy section, and is arranged to beattached to a lug 28 carried by one ofthe heatin sections 6, whereby thelower end of the ummy section may be securely held in place.

Beneath the heater box is disposed a tra 29, which is provided at itsont end wit a nipple 30, which connects the apertures 12 in the adjacentheater sections. This trap is also provided at its rear end with anipple 31, which registers with and connects the openings 13 in theadjacent sections. A branch 32 is also provided at the rear end of thetrap, to which is connected the exhaust pipe 33. The exhaust pipe 33 isconnected by suitable piping to an exhaust blower 34 of any suitabletype.

It will be seen that when the blower 34 is operated and the pressurewithin the heater box 7 is less than the atmosphericpressure, the dropair intakes 21 will be closed and a substantially air tight systemprovided. When the burner is lit the heat generated will pass outthrough the openings 11 in the nipples 17 and into the upper ends ofeach of the heating sections 6 and 6. As the heat in the central membersof the heating sections increases, it will descend I until it reachesthe lower end of the central members, where it will pass into theforward part 10 of the exterior member 10 and rise to the upper endthereof. As there is a slight suction at the openings 13, formed at thelower end of each rear part 10 of the exterior members 10, this heatedair will be drawn down to the lower end of the said rear part, and thusbe substantially equalized in pressure and heat. It will thus beseenthat the heater box 7 and the'central members 10'of the heatingsections may be heated to a high degree, while at the same time theexterior members 10 are considerably cooled by radiation into theatmosphere, thus reducingto a minimum the liability of injuring personsor articles coming incontact therewith.

The liquid condensation, which is formed by the burning gas, will draininto the lower part of the central members 10, pass through the openings12 therebetween and then flow of the details herein shown and describedmay be made without departing from the spirit of my invention or thescope of the appended claims, and I do not-wish to be limited to theexact embodiment herein shown and described.

Having thus described my invention, what I claim is:
